This column has covered cloud native and related relevant standards since the inception of the magazine. Recent progress in this area has received additional impetus from participation by major organizations in the standards-based development process. A milestone in this proces s has been provided by Microsoft and AWS joining the Cloud Native Computing Foundation, along with other cloud standards...
This paper examines advantages of cloud while supporting real-time service systems using Salesforce platform. We build here a service management platform for the Polish Billiards and Snooker Association (PBSA), based on a real-time system located in a cloud. It allows PBSA managers accomplish tasks in this system on-demand. And, it is deployed as a private cloud to grant an access only to the employees...
Despite their increasing proliferation and technical variety, existing cloud storage technologies by design lack support for enforcing compliance with regulatory, organizational, or contractual data handling requirements. However, with legislation responding to rising privacy concerns, this becomes a crucial technical capability for cloud storage systems. In this paper, we introduce PRADA, a practical...
In assessing the validity of security claims, assurance cases are an effective approach to help refine the claims, collect detailed evidence, narrow options, and structure a convincing and valid argument to justify the resulting decision.
High performance applications requires high processing power to compute highly intensive and complex applications for research, engineering, medical and academic projects. In the traditional way, an organization will have to pay very high costs to run an HPC (High Performance computing) application. The organization has to purchase highly expensive hardware for running an HPC application and maintaining...
End-to-end latency of serving jobs in distributed and shared environments, such as a Cloud, is an important metric for jobs' owners and infrastructure providers. Yet it is notoriously challenging to model precisely, since it is affected by a large collection of unrelated moving pieces, from the software design to the job schedulers strategies. In this work we present a novel approach to modeling latency,...
Cloud computing is a fast-growing paradigm that has forcefully emerged and established itself in the next generation of IT industry and business, performing massive-scale and complex computing. As cloud technology adoption continues to progress, massive growth in the scale of data generated through cloud computing has been observed. A large part of that data has been machine-generated log data; it...
The paper describes the creation of a novel cloud broker created to provide efficient cloud brokering services for a government organization in India — the BroCUR. The BroCUR works in a volunteer federated, distributed schema with control being executed using a combination of threshold based metrics and triggers which launch task migration. The novel aspect of the BroCUR is the inclusion of the human...
Cloud computing offers an innovative business model for organizations to adopt IT services at a reduced cost with increased reliability and scalability. However organizations are slow in adopting the cloud model due to the prevalent vendor lock-in issue and challenges associated with it. While the existing cloud solutions for public and private companies are vendor locked-in by design, their existence...
For some years now, the concept of Cloud Computing (CC) is presented as the new revolution of information technology. It presents not only a technical innovation for better IT system flexibility, improvement of working methods and cost control, but also a new economic model, built around the concept of IT Services that are identifiable, classifiable and countable for end users, who can benefit by...
E-health is becoming more important in today's technological world. Healthcare is increasingly being supported by IT applications such as the emergence of cloud computing. But what are the challenges when using cloud computing in e-health?
This paper presents a comprehensive study on the challenges and issues of security in cloud computing. We first look into the impacts of the distinctive characteristics of cloud computing, namely, multi-tenancy, elasticity and third party control, upon the security requirements. Then, we analyze the cloud security requirements in terms of the fundamental issues, i.e., confidentiality, integrity, availability,...
